The sample has been inserted into the furnace too quickly:
– See Operation Manual chapter “Applications / Coal analysis”.
The sample weight is too high:
– If a sample burns explosively, then there could be a shortage of oxygen. This can cause
some soot or oil vapors that pass through the hot zone of the furnace without burning. It
is necessary to reduce the weight of the sample, e.g. to 100mg or even to 50mg. If the
weight reduction doesn’t help, then operate differently by shifting the boat slowly towards
the beginning of the hot zone of the furnace. Leave the boat there and allow the sample
to start burning. Towards the end of the combustion, move the boat to the middle of the
hot zone, in order to obtain a complete combustion. See Operation Manual “Applications
/ Oil analysis”.
The sample is metallic:
– Perform analysis by using the induction furnace. See Operation Manual.
